Hi all
Just had a fault crop up on my 2012 A4 CGLC Quattro where it drops into limp mode and throws the ESC Light on with a flashing Glow plug light.
Plugged it in when I got home and seen there was a few fault codes on the Sensor Reference Voltage B - Open Circuit.
When the fault comes on, either running or sat with ignition on, the revs increase to 1000rpm over standard 750rpm and the lights mentioned above illuminate. Theres also a change in engine note and engine is pretty shuddery when stopping. Upon restarting, it can often turn over a couple turns rather than firing up straight away.
Only things done to the car is a ECU remap and a EGR blank (remapped due to EGR throwing codes up causing limp about 2 years ago and been perfect since)
Ive included a full VCDS scan below for reference.
Any help appreciated.
Chris
